Abstract
A method and apparatus for electrical discharge or electrochemical machining of workpieces, in which a machining electrode is moved relative to a workpiece, the machining is performed in cycles, and the appropriate process parameters are adjusted for machining of the current cycle with consideration of process parameters of the current cycle. To improve this method and the apparatus to the extent that improved geometric machining accuracy is made possible without time losses, stored process parameters of at least one previous cycle are also considered for adjustment of the process parameters of the current cycle.
